Just like the Ontario fishing License, we don't have a test you must pass before joining Muskies Canada...Not all our members are 'experts'. I'm certainly not. Though I do pride myself on being a good fish handler, and not just Muskies!
I could see flexing when I bounced the motor on the trailer, (place foot on ride plate, bounce) Then I took the transom cap off and same thing, I could easily shove a 1/16'' metal pin down 10" anywhere I tried!
This thread shows how 'do-able' this is. Helps if you have a nice garage/shop I realize. I removed my Yamaha F90 and hung it from the rafters in my garage, If that's more than you wanna do you can take it to your marine mechanic, pay them to R&R/store it.
